Control arm camber bolt washer play Help Plz.

There is no rust, all washer are in place, bracket is in tact and nothing is broken.

On the bracket though I am noticing some significant wear around the border where the washers sit and where the adjustments Occur possibly it widened over time and it's causing to misadjust by movement and weight of car? This is only a theory though not 100% confirmed.. During adjustment and tighting it does lock in place but I'm thinking with heavier weight this could be the issue. Where it's coming undone.
